As the title suggests, I would like to get the last word out of an NSString. I thought using this code:

NSArray *listItems = [someNSStringHere componentsSepa

If you wanted to use a regular expression (which can be useful if you want to start getting more complicated in terms of what you're looking for at the end of your string), you could do something like:

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"\\S+\\Z" options:0 error:nil];
NSTextCheckingResult *found = [regex firstMatchInString:inputString options:0 range:NSMakeRange(0, [inputString length])];

if (found.range.location != NSNotFound)
    result = [inputString substringWithRange:found.range];
